Sure, some bands put out opportunities for trenage boys to vent. But they also CELEBRATED things. Just having a good time. Just being alive. Just getn wild! Fun! Grunge never celebrated a damn thing. It was depressing. It was angry. It was messy. Sure, I'm fine with "raw". But lighten up a little! And (in my region) it never translated well for cover bands. Neil Young and the Allmans had a bit of a comeback at that time. You could get away with playing their stuff. The occasional STP song went over well. But nobody wanted to have a beer over grunge music. Nobody wanted to crowd up to the stage or fill tue dance floor to grunge. They wanted to stand back with their untucked plaid flannel shirts (each if them expressing their individuality.... only exactly like everyone else) and their hands in their pockets looking too "cool" to let loose and have fun. DJs took over here because live music was painted into a box. You couldn't play Boston or Bad Company because that stuff was "selling out". You couldn't play grunge because nobody wanted to party to it. And, after all, partying is why people go to bars.
It was awful to watch unfold. Club owners banged their heads against the wall trying to keep live music going. Bit nobody had an appetite for LOCAL and/or cover bands.
That's 180° the opposite affect it had in my part of the world.
Live music absolutely exploded.
Suddenly
every bar was clamouring for live acts - bars that had never previously hosted live music.
Every couple of months, there was a Battle Of The Bands competition, with categories for just about every genre.
There were suddenly national music days, where outdoor venues would pop up, for local mini-festivals, with a wide mix of genres.
Practically every teenager, and early 20-something had their own originals band, which also brought out all of the older originals bands, and secured an appreciative audience for all of the blues bands, jam nights, and covers bands.
You couldn't go to a pub for a quiet pint, even on a Sunday afternoon, without a band playing in the corner, or in the beer garden.
It was really musically diverse, and vibrant.
After the Grunge bubble burst, there was a bit of a decline, but there was a lot of original Garage Rock, and Psychedelic Rock, Jungle / Drum & Bass stuff around.
Then Brit Pop happened and the live scene was rejuvenated again (though not to the same degree as during peak Grunge).
After that, live music dropped off a cliff, at the local level (it still existed, but with nothing like the presence it had in the early 90's), but it was still thriving in dedicated venues.
